A viral video circulating on social media has sparked heated discussion online after a man was filmed rocking his car while pumping petrol at a fuel station. The unusual behaviour, which appeared to show the driver shaking the vehicle in an attempt to “fit more fuel” into the tank, quickly drew thousands of comments and reactions.
The clip, originally shared on Facebook shows the man moving his car from side to side while refuelling. According to the post, the driver allegedly attempted to squeeze every last drop of petrol into the tank amid rising fuel prices in the region.
The video quickly spread across social media platforms, with many users debating whether such a method could actually increase the amount of petrol a vehicle can hold.
Rising Petrol Prices Fuel Online Debate
The viral post compared fuel prices in Malaysia and Singapore, highlighting the significant difference between the two countries. According to the comparison shared in the post, Malaysia’s RON97 petrol was listed at around RM3.85 per litre, while premium petrol in Singapore was estimated at about S$3.90 per litre.
The contrast immediately triggered a wave of comments discussing cross-border fuel costs and the impact of global oil prices on drivers. Some commenters suggested the driver might have been trying to maximise the amount of petrol in the tank because of the higher cost of fuel in Singapore.
Others defended the driver, pointing out that he appeared to be pumping higher-grade petrol, which is not subsidised in Malaysia and therefore permitted for foreign vehicles.
However, the discussion soon shifted away from prices and towards whether shaking a vehicle while refuelling actually makes any difference.
Can Shaking a Car Really Fit More Petrol?
Experts say the idea likely stems from how some solid materials behave when shaken. For example, shaking a container filled with grains or rice can reduce air gaps and allow more material to settle inside.
Petrol, however, is a liquid and naturally flows to fill available space in a fuel tank. Because of this, rocking a car typically does not create additional room for significantly more petrol.
Modern fuel pumps are also designed with automatic shut-off mechanisms. These systems detect pressure changes when the tank is nearly full and stop the flow of petrol to prevent overflow.
At most, rocking the vehicle might allow small air pockets inside the tank or fuel line to shift slightly, but the difference would likely amount to only a very small volume of fuel.
Safety Concerns Raised by Viewers
Aside from the debate about petrol capacity, some viewers also raised concerns about safety. Fuel stations are considered high-risk environments because petrol vapours are highly flammable.
Shaking a vehicle vigorously while refuelling could potentially increase the risk of spills, which can create safety hazards at the pump.
Others also pointed out that filming at petrol stations while standing near refuelling vehicles may not be advisable, particularly if mobile phones are being used close to fuel vapours.
Despite the criticism, many commenters also questioned why the driver was being filmed and posted online, saying that the act itself was harmless and largely a personal choice.
The short video has since become another example of how everyday situations — especially those involving petrol prices, cross-border travel and cost of living — can quickly turn into viral discussions on social media.
